on D-branes

This is an introduction to the physics of D-branes. Topics covered include Polchinski’s original calculation, a critical assessment of some duality checks, D-brane scattering, and effective…

Curvature terms in D-brane actions and their M theory origin
- C. Bachas, P. Bain, M. B. Green
- Mathematics
- 24 March 1999
We derive the complete (curvature)2 terms of effective D-brane actions, for arbitrary ambient geometries and world-volume embeddings, at lowest order (disk-level) in the string-loop expansion. These…
Flux stabilization of D-branes
- C. Bachas, Michael R Douglas, C. Schweigert
- Mathematics
- 6 March 2000
We explain how D-branes on group manifolds are stabilized against shrinking by quantized worldvolume U(1) fluxes. Starting from the Born-Infeld action in the case of the SU(2) group manifold we…
Anti-de Sitter D-branes
- C. Bachas, M. Petropoulos
- Physics
- 25 December 2000
We study D-branes of the SL(2,) WZW model and of its discrete orbifolds. Gluing the currents by group automorphisms leads to three types of D-branes: two-dimensional hyperbolic planes (H2), de Sitter…
Permeable conformal walls and holography
- C. Bachas, J. Boer, R. Dijkgraaf, H. Ooguri
- Physics, Mathematics
- 23 November 2001
We study conformal field theories in two dimensions separated by domain walls, which preserve at least one Virasoro algebra. We develop tools to study such domain walls, extending and clarifying the…
A WAY TO BREAK SUPERSYMMETRY
- C. Bachas
- Physics
- 6 March 1995
I study the spontaneous breakdown of supersymmetry when higher-dimensional Yang-Mills or the type-I $SO(32)$ string theory are compactified on magnetized tori. Because of the universal gyromagnetic…
Spin-2 spectrum of defect theories
We study spin-2 excitations in the background ofthe recently-discovered type-IIB solutions of D’Hoker et al. These are holographically-dual to defect conformal field theories, and they are also of…
Aspects of type I– type II– heterotic triality in four dimensions

Fusion of conformal interfaces
- C. Bachas, I. Brunner
- Physics
- 1 December 2007
We study the fusion of conformal interfaces in the c = 1 conformal field theory. We uncover an elegant structure reminiscent of that of black holes in supersymmetric theories. The role of the BPS…
